Andrew Sharpley, Ph.D.

Distinguished Professor, Department of Crop, Soil and Environmental Sciences

Dr. Andrew Sharpley is an international authority on assessing, managing, and remediating the impacts of agricultural management on soil and water resources.

His research investigates the cycling of phosphorus in soil-plant-water systems in relation to soil productivity and water quality and includes the management of animal manures, fertilizers, and crop residues. 

He also evaluates the role of stream and river sediments in modifying phosphorus transport and response of receiving lakes and reservoirs.

Most recently, Sharpley developed decision-making tools for agricultural field staff to identify sensitive areas of the landscape and target management alternatives and remedial measures that have reduced the risk of nutrient loss from farms.

He currently serves as co-director of the Arkansas Discovery Farm Program, co-chair of the Division of Agriculture’s Environmental Task Force, on National Academy of Science Committees, and is a member of EPA’s Scientific Advisory Board. 

Sharpley has authored or co-authored over 550 publications with the impact of this published research evidenced by his refereed journal papers being cited 18,508 times since 1980, according to an ISI Web of Knowledge science citation index search.

Sharpley is Editor-in-Chief of the Soil Science Society of America and an editor of the Journal of Environmental Quality.  

In 2008, he was inducted into the USDA-ARS Hall of Fame, and in 2012 received the Distinguished Agriscience Scientist Award from the Christopher Columbus Fellowship Foundation.
